OPCMD or OPERCMDS will not provide this security. The only DB2 command where these calls occur is for the
'-DC11 START DB2' commands. In that case you would see the following calls for each Class:
========================================================
ACID CLASS ENTITY NAME
Issuing user OPCMD START
Issuing user OPERCMDS MVS.START.STC.DB1BMSTR
DB2 STC OPCMD START
DB2 STC OPERCMDS MVS.START.STC.BRLMPROC
DB2 STC OPCMD START
DB2 STC OPERCMDS MVS.START.STC.DB1BDBM1
========================================================
Neither OPCMD nor OPERCMDS is checked for other DB2 commands such as DISPLAY or STOP. In those cases
the only external security command checking is performed by either TSS/DB2 (if used) or the DB2 external
security authorization exit (
[email protected]). Without these security features/products no external security checks
will occur for DB2 commands.
